There can be various problems with biodiesel these problems can be caused by storage conditions, manufacturing flaws, or contamination. Biodiesel is an excellent cleaner and will remove deposits from your tank, it can unblock fuel filters and injectors. There are few problems associated with biodiesel meeting astm specifications.
B5 or 5% biodiesel would be the limit I would use in any tractor at least at the current level of biodiesel formulations. In the winter biodiesel does cause more problems so be more careful.

ANSWER:Normal diesel fuel should not be burned in a kerosene heater, because there are many more contaminants in it, such as sulfur. A 100% solution of Biodiesel will not work because it requires a much higher initial temperature (300F) to burn cleanly. Blends of these fuels with kerosene can be burned, but there may be problems with the fuel soaking up the wick properly in the case of Biodiesel, which can lead to wick burning and sooting. There may also be problems lighting and burning properly if the blend contains too much of the Biodiesel, as its flash point is higher than kerosene. Diesel/Biodiesel fuel can also be run in many forced air heaters along with kerosene.
Yes it is safe to mix petroleum diesel and biodiesel. Blends of biodiesel and petroleum diesel are designated "BX." Where "B" states that the fuel mixture is a biodiesel blend and "X" indicates the percentage of biodiesel in the blend. For example, common blends of biodiesel in North America include B2 (2% biodiesel), B5(5%), B20(20%), and B100(100%). B100 is also know as "neat," or pure, biodiesel.
Wikipedia provides an excellent encyclopedia style article on biodiesel fuel. Other websites that offer information about biodiesel fuel are the U.S. Department of Energy's Biodiesel page and the National Biodiesel Board's page.
Yes, you can buy a hybrid that uses biodiesel but they are much harder to come by than hybrids that don't use biodiesel or biodiesel cars that aren't hybrids.
the biodiesel should be used in the diesel engine, and there are some biodiesel motorbike has been produced such BWM http://www.doinggroup.com/
Just about any diesel vehicle will run on biodiesel.
Biodiesel's weight is generally 7.34 lbs/gal.

You often only find biodiesel in the Midwest or areas where corn is a big market. Biodiesel is made out of corn and that's why. Biodiesel will make your diesel engine get better gas mileage just so you know.
